Product description: Revolution Pi RevPi Core 3+ 8 GB eMMC
RevPi Core 3+ module based onRaspberry Pi CM3with quad-core processorBCM2837B0 ARM Cortex-A53 clocked at 1.2 GHz, designed for industrial applications. The minicomputer is equipped with 1 GB of RAM,8 GB of eMMC memoryand a real-time clock chip,as well as an Ethernet port, two USB 2.0 connectors, a microUSB port and microHDMI. RevPi runs on a specially modified version of Raspbian with RTC support pre-installed. RevPi Core 3+ is poweredfrom 12 V to 24 V DCand enclosed in a DIN rail mounted enclosure. It supports Modbus protocol and can be programmed in Node-RED environment.

RevPi Core 3+ power supply
The power supply is one of the most important components of the Revolution Pi minicomputer. It uses ahigh-quality DC-DC converter(with an efficiency of over 80%) with an input voltage of24 V, which emits as little heat as possible. RevPi Core 3+ can also be powered with a lower voltage of 10.2 V, but the manufacturer recommends power supply from min. 12 V. With 24 V power supply the loss of power for25 mswill not affect the RevPi operation (no load on USB ports). The device is protected against high electromagnetic interference and electrical discharges. The module is powered through thescrew connectorsat the bottom of the case. Thanks toRTC chip, date and time will always be up-to-date.
RevPi Core 3+ interfaces
RevPi Core 3+ has a number of important communication interfaces.
- An RJ45 Ethernet port for connecting to a LAN.
- Two USB type A connectors to which you can connect USB 2.0 client devices. Both connectors have 5 V / 500 mA output, which allows you to connect various types of USB drives, flash drives, without using an active USB hub.
- The microUSB connector can work as a USB host system, e.g. to connect RevPi to the computer for the first flashing.
- MicroHDMI connector for screen connection.

Modular design of the RevPi Core 3+
Revolution Pi RevPi Core 3+ has aPiBridgeconnector located on the top. It is used to connect the Revolution Pi expansion modules, these are:
- 4 PiBridge pins used to automatically detect the connected module when the RevPi starts up, the RevPi Core knows exactly what device is connected and what physical position it is in.
- 4 PiBridge pins for fast exchange of small data packets via RS485. This channel is also used to configure the module during the boot-up phase. Once configured, it is used for cyclic data exchange between the RevPi Core and all connected IO modules.
- 8 PiBridge pins for fast exchange of large data packets over the Ethernet port. Channel used only by gateway modules, which can cyclically accumulate up to 512 bytes of data from almost all buses.
RevPi Core 3+ meets industrial requirements
Revolution Pi aimed to use the Raspberry Pi in an industrial environment to become a true IPC that meets the EN 61131-2 standard.
- Power supply: 12 V to 24 V DC, max. 10 W
- Operating temperature: from -40°C to 55°C
- ESD protection: 4 kV / 8 kV according to EN 61131-2 and IEC 61000-6-2

Raspberry Pi vs Revolution Pi
Standard versions of the Raspberry Pi are small modules equipped with interfaces found in standard PCs. The Raspberry Pi Foundation has created an inexpensive boardfor educational purposes. The Revolution Pi modules were based on the Raspberry Pi Compute Module board, for which Kunbus created an evaluation board, creating a controller with the same specifications as classicPLCs. Revolution Pi was created forindustrialapplications with the possibility of expanding its capabilities through modules with IO interfaces and communication modules.
